AMALGAMATOR.

SEECIFIOATION forming part of Letters Patent No. 272,741, dated February20, 1883,

Application filed June 7, 1882. (No model.) I

To all whom it may concern Be it known that l,\/VILLIAM MoLLER, acitizen ofthe United States, residing at Yonkers, in the county ofW'estchester and State of New York, have invented new and usefulImprovement in Amalgamators, of which the following is a specification.

This imention relates to that class of amalgamators for which I tiled anapplication for Letters Patent on or about the 11th day of May, 1882;and it consists in the novel combination of parts hereinafterdescribed,whereby the operation of the apparatus is facilitated orimproved.

This invention is illustrated ii the accompanying drawings, in whichFigure l represents a vertical central sei-tion. Fig. 2 is a plan or topview of the agitator-disk. Fig. 3 is an inverted plan view thereof. Fig.at is a plan or top view of the amaIgamating-pan, showing also theore-dist rihuter. Fig. 5 shows a portion ofthe agitator-disk in sideview. Fig. 6 is an inverted plan view of one of a series of scrapers,combined with concentric segments in the pan, as hereinafter explained.Fig. 7 is a cross-section of the scraper, showing it attached to asegment. Fig. 8 is alongitudinal section thereof. Fig. 9 is across-section, showingscoops forcatchingoverflowingmetal. Fig.

10 is a plan or top view thereof. Figs. 11 and 12 are detail views.

Similar letters indicate corresponding parts.

The letter A designates the amalgamatingpan, containing a revolvingagitator-disk, B, which is fixed to a vertical shaft, 0, and therebysuspended from a timber, I). This shaft 0 is hollow, and within it isarranged a second hollow shaft, E, which is suspended from a timber, E,and carries a revolving distributer, F, the latter being situatedbeneath the agitatordisk and next above the bottom of the pan. Both thedisk-shaft O and the distrilmter-shaft F are provided with a pulley,O F,for imparting motion to the disk and distributer. and in practice thedistribnter is made to revolve with a higher speed than the disk, itsaction being to throw the ore which is deposited in the pan through thedistributer-shaft outward by centrifugal force. On the circumference ofthe agitator-disk B and on the side of the pan are arranged alternatingblades 8 or 8, serving to check the mineral finding its way to the sideof the pan, while allowing the escapeot sand. In the body of theagitator-disk B are formed openings 0, and above said disk is arranged asecond disk, I, which is stationary, it being secured to the side of thepan, as by means of arms r. )lVhen the machine is applied to use thesand escapes upward through the disk-openings 0. and, coming in contactwith the stationary disk I, it is forced outward to the side of the panbetween the stationary disk and the revolving disk, due to the motion ofthe latter. Said disk-openings 0 are of segmental shape, and arearranged concentrically to each other and the disk-axis, thus affordinga ready means of escape to the sand,since the openings are in theplaneof motion ofthe disk. In order to keep the stationary disk I freeof sand, the upper surface of the revolving disk B is provided withscrapers n, and the stationary disk is arranged approximately in contacttherewith, the scrapers being of equal height, so that the lower surfaceof the stationary disk is exposed to the action of the scrapers. Saidscrapers a are composed of vertical blades, and they are arrangedobliquely to the axis of the revolving disk, so that they perform theadditional function of working outward the sand that is received betweenthe disks, as before stated.

The bottom of the amalgamating-pan A is provided with concentricsegments J, and on thelower surface of the agitator-disk B arecorresponding segments, J, which alternate with those of the pan incircular planes, so that while the two series of segments clear eachother in the revolution of the disk they co-operate to retard theprogress of the ore from the center to the circumference of the pan.Each of these segments J of the pan carries ascraper, K, which acts onthe lower surface of the agitator-disk B to keep it free of sand, saiddisk revolving approximately in contact with the scrapers. For thepurpose of attaching the scrapers K to the pan-segments, each segment isformed with a transverse notch, u, in the upper edge, (best seen in Fig.8,) and each scraper is provided on its lower surface with a groove, 1,which is fitted t0 the segments, and with a key, I, in said groove,which is adapted to the notches of the segments, so that, it thescrapers are placed on the segments by means of their grooves and thekeys are brought into the notches, the scrapers are held against bothlongitudinal and lateral displacement in one direction by the sides ofthe notches and in the other direction by the sides of the grooves,while such means of attachment at the same time renders the scrapersdetachable. Another advantage gained by said attachment is that thescrapers, being loose, are permitted to adapt themselves to anyirregularities on the lower surface of the agitator-disk. The segments Jof the agitator-disk are formed with teeth p in their lower edges, (seeFig. 11,) so that the segments form agitators to stir up or scatter thecontents of the pan, and the leading edges of these teeth are oblique tothe axis of the disk, as shown in Fig. 12, causing them to act on thematerial with a tendency to throw it outward to the side of the pan.

The stationary disk I is provided with an annular cell, '0, near thecenter thereof, and with holes a in the bottom of such cell, while tothe side of the pan A are secured scoops o one or more, adapted to emptyinto the cell 2;. These scoops extend inwardly on an incline plane, andtheir receiving ends are above and opposite to the edges of both therevolving disks B and stationary disk I, such ends being curved, sothatin case any metal overflows the edges of the disks it is caught bythe scoops, and thereby conducted to the cell 12, whence it returns tothe pan through the holes e and the holes 0 of the revolving disk.

What I claim as new, and desire to secure by Letters Patent, is

1. The combination, substantially as hereinbel'ore set forth, with theamalgamating-pan, of the revolving agitator-disk having openings adaptedto permit the upward escape of sand, and the stationary disk situatedabove said agitator-disk.

2. The combination, substantially as hereinbefore set forth, with theamalgamating-pan, of the revolving agitator-disk having segmentalconcentric openings for the upward escape of sand,and the stationarydisk situated above said agitator-disk.

3. The combination, substantially as hereinbefore set forth, with theamalgamating-pan, ofthe revolving agitator-disk having openings adaptedto permit the upward escape of sand, and having its upper surfaceprovided with scrapers, and the stationary disk arranged above saidagitator-disk in contact with the scrapers.

at. The combination, substantially as hereinbefore set forth, with theamalgamating-pan, of the revolving agitatordisk having openings adaptedto permit the upward escape of sand, and having its upper surfaceprovided. with scrapers, which are arranged obliquely to the axis of thedisk, and the stationary disk arranged above said agitator-disk insuperficial contact with the scrapers.

5. The combination, substantially as hereinbefore set forth, of theamalgamating-pan having its bottom provided with concentric segments,and with scrapers attached to said segments, and the agitator-diskhaving its lower surface provided with concentric segments whichalternate with those of the pan, and revolving in contact with saidscrapers, for the purpose specified.

6. The amalgamating-pan having its bottom provided with concentricsegments, each containing a. transverse notch, and the scrapers having agroove which is fitted to the segments, and a key in said groove, whichis adapted to the segment-notches for the purpose of attachingsaidscrapers to the segments, in combination with the revolvingagitatordisk.

7. The combination, substantially as hereinbefore set forth, with therevolving agitatordisk,'of the concentric segments having their loweredges provided with teeth, for the purpose specified.

8. The combination, substantially as hereinbefore set forth, with therevolving-agitatordisk, of the concentric segments having their loweredges provided with teeth, the leading edges of which are oblique to thedisk-axis, for the purpose specified.

9. The combination, substantially as hereinbei'ore set forth, of thestationary disk having the centralannularcell provided with holes in thebottom thereof, the revolving disk, and the inclined scoops, one ormore, having their receiving ends arranged above the edges of the disksand emptying-into the cell of the stationary disk, for the purposespecified.

In testimony whereof I have hereunto set my hand and seal in thepresence of two subscribing witnesses.
